U.S. energy-related CO2 emissions drop 25% to 38% below what they were in 2005 by 2030, according to our projections in the Annual Energy Outlook 2023 (AEO2023). We use 2005 as an emissions reference year because the United States’ nationally determined contribution (NDC), submitted as part of the Paris Agreement, calls for a target of 50% to 52% of net greenhouse gas emissions below the 2005 level by 2030. It’s important to note, however, that we only consider energy-related CO2 emissions, which does not cover the full NDC scope.
